I would like to create a simple log file for a shared workbook I have.
Preferably I'd like the log to be on a hidden worksheet within the
workbook. All I need to capture is the userID, Date/time the workbook
was opened, and the date/time the workbook was closed. Can some one
tell me how I would go about doing this. I imagine I would have to use
some VBA to accomplish this. Thanks.
